With three years still left until publication, the fights over the new version of the psychiatric diagnostic manual, the DSM-V, are hotting up and The New York Times has a concise article that covers most of the main point of contention.

- “What you have in the end,” Mr. Shorter said, “is this process of sorting the deck of symptoms into syndromes, and the outcome all depends on how the cards fall.”

- Psychiatrists involved in preparing the new manual contend that it is too early to say for sure which cards will be added and which dropped.

Although I doubt the DSM committee are using that exact metaphor, it certainly illustrates the point that the process requires a certain degree of value-judgement.

It’s interesting, however, that the public debate is currently focused on whether certain diagnoses should be included or not, rather than whether diagnosis itself is useful for psychiatry.

We’ve had psychometrics for a good 100 years that allow us to measure dimensions of human experience and performance with a much greater degree of accuracy than Read the rest of this entry »

Playing the Blame Game
– Video games stand accused of causing obesity, violence, and lousy grades. But new research paints a surprisingly complicated and positive picture, reports Greater Good Magazine’s Jeremy Adam Smith.

Cheryl Olson had seen her teenage son play video games. But like many parents, she didn’t know much about them.

Then in 2004 the U.S. Department of Justice asked Olson and her husband, Lawrence Kutner, to run a federally funded study of how video games affect adolescents.

Olson and Kutner are the co-founders and directors of the Harvard Medical School’s Center for Mental Health and Media. Olson, a public health researcher, had studied the effects of media on behavior but had never examined video games, either in her research or in her personal life.

And so the first thing she did was watch over the shoulder of her son, Michael, as he played his video games. Then, two years into her research—which combined surveys and focus groups of junior high school students—Michael urged her to pick up a joystick. “I definitely felt they should be familiar with the games if they were doing the research,” says Michael, who was 16 at the time and is now 18.

Olson started with the PC game Read the rest of this entry »

1) There were a few interesting research papers presented at the last  American Psychological Association conventions around the theme:

Playing Video Games Offers Learning Across Life Span, Say Studies
–Skills Transfer to Classroom, Surgical Procedures, Scientific Thinking (press release).

Probably the most interesting study was that of 303 laparoscopic surgeons, which “showed that surgeons who played video games requiring spatial skills and hand dexterity and then performed a drill testing these skills were significantly faster at Read the rest of this entry »

The article Clumsy kids more likely to become obese adults: study (CBC)…

- “The study was based on tests of about 11,000 people in Britain who were tested for hand control, co-ordination and clumsiness at age seven and 11, and were then followed until age 33.”

- “Prof. Scott Montgomery of the Karolinska Institutet in Stockholm and his colleagues at Imperial College London in England said they purposely chose measurements of fine hand control such as picking up matches, rather than those likely to be influenced by participating in sports, such as catching balls.”

- “While it is often assumed that the cognitive impairments seen in adult obesity are a consequence of excess weight, that could be putting the chicken before the egg, the researchers say”

…reminds me of Judith Beck’s words on how to “Train Your Brain to Think Like a Thin Person”

- “The main message of cognitive therapy overall, and its application in the diet world, is straight-forward: problems losing weight are not one’s fault. Problems simply reflect lack of skills–skills that can be acquired and mastered through practice. Read the rest of this entry »
